ALTER OPERATOR
changes the definition of an operator\&. The only currently available functionality is to change the owner of the operator\&.
.PP
You must own the operator to use
ALTER OPERATOR\&. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have

privilege on the operator\*(Aqs schema\&. (These restrictions enforce that altering the owner doesn\*(Aqt do anything you couldn\*(Aqt do by dropping and recreating the operator\&. However, a superuser can alter ownership of any operator anyway\&.)
